To @ZZ whom it may concern:

Beit known that I, LEONARD PAGET, a citizen of the UnitedStates,residing at New York,

in the county of New York and State of New York, have made a new anduseful Invention in Portable Electric Lamps, of which the following is aspecification.

My invention relates particularly to iinprovernents in that type ofportable electric lamps which utilize batteries as the source ofcurrent-supply-such, for instance, as are used in connection with handlamps or lanterns, bicycles, carriages, and analogous vehicles 3 anditsobjects are, iirst,to devise such a lamp as will be compact instructure, with the parts and circuit connections so arranged orconstructed that they will withstand` the ordinary shocks and usage intransportation without detriment thereto; second, to so arrange saidparts that the batteries may-be quickly and readily removed from theretaining-casing when it becomes necessary to restore or replenish them;third, to construct the supporting` parts of the battery in the natureof metallic casings,and to combine therewith a lamp and a reflector insuch manner that the casings constitute the conductors of the currentfrom the battery to the lamp, thereby avoiding the use of wires asconductors.

My invention will be-fully understood by referring to the accompanyingdrawings, in which- Figure 1 is a side elevational view of the entirestructure, and Fig. 2 aplan view of the top portion thereof. Fig. 3 is avertical sectional view taken through Fig. 1, the reflector being shownin broken section. Fig. 4 is a horizontal sectional view taken on theline Q3 0c, Fig. 3, the reector and lamp being removed.

Referring now to the drawings in detail, A and A' represent two tubularmetallic retainingcasings, and K and K metallic heads or caps therefor,provided with bayonet-andsocket connections, the pin connection beingattached to theinner portions of the retainingcasings and the bayonetconnection grooved in the outer surface of the heads or caps K and K',as will be obvious on inspection of Fig. 8.

C represents a cylindrical clamp or clip, provided on one side with twolugs or ears L and on the other with a neck N, screw-threaded interiorlyfor the purpose of receiving the screw-threaded neck S of a metallicreflector R, which neck in turn is provided with an opening and interiorscrew-threads adapted to receive the screw-threaded portion of anincandescent lamp L.

B and B represent two metallic battery* cups, preferably of copper, forretaining the battery solution, and E E are the active electrodes,hermetically sealed therein, said electrodes being of any preferredform, either in the nature of a dry battery or a storage battery of anypreferred structure, the retaining-cups B and B constituting thepositive poles of the battery and the electrodes E E the negative polesthereof, the arrangement being such that when the solution is inposition in the hermeticallysealed cups and the cups in turn in positionin the retaining-casings A and A the lower cup B will rest upon theinner surface of the bottom cap K and the upper cup B will rest upon thenegative electrode E of the lower cell, P beinga metallic thumb-screwadapted to be screwed through the upper cap K against the electrode E, Rbeing a softrubber ring for effectually sealing the upper portion of thebattery.

The inner and outer surfaces of the casing A are coated with insulatingmaterial, preferably a thick coating of japan, and the outer surface ofthe lower casing A is similarly coated to a point near the lower edge ofthe clamp O, the coating being discontinued at this point for thepurpose of making good electrical connection between the outer surfaceof the casingA and the said clamp O, as clearly illustrated in Fig. 2 ofthe drawings.

s is a conducting-spring secured to the lower end of the metallic casingA but beneath the insulating-coating, its free end being adapted to bearagainst the inleading conductor of the lamp L, the outleading conductorof which is connected to the screw-threaded portion of the lamp andhence to the conducting-necks S and N, the circuit being from theinleading conduct-or of the lamp through the spring 3, the metallicshell A', cap K', screw-plug l?, electrode E, through the batterysolution from the cup B to thev lower inner electrode E, thence throughthe battery solution of the IOO lower cup B to said cup, finally throughsaid cup to the lower cap K, to the retaining shell or casing A, back tothe neck N in the screwthreaded portion of the lamp through the filamentto starting-point.

In order to put the parts together, the screws in the rear side of theclamp or clip C are simply removed and the casings A and A inserted inthe manner shown in Fig. 3, after which the screws are driven firmlyhome, so as to firmly clamp or clasp the shells in the position shown.The lamp, and its reiiector, is then screwed into the neck N and isready for use. Then it is desired to disconnect the lamp, it is onlynecessary to withdraw the thumb-screw P until the circuit is broken.

I do not limit myself to the especial details of construction hereinshown and described, as the same might be departed from in a number ofrespects and still come within the scope of my claims herein after made.To illustrate, the heads or caps K and K might be screwthreaded and theinterior of the cups correspondingly screwthreaded to receive the same,or the tubular retaining casings or shells A and A might be made each ofa single piece of metal of cup-like form, the upper one having theopening for the thumb-screw P or any analogous switch which might beused for closing and interrupting the circuit, the lower or open end ofthe upper retaining-casing A and the upper end of the lowerretaining-casing A being provided with bayonet-pins adapted to iit intobayonet-grooves in the body part of the clamp C, the necessaryinsulation of course being provided for the upper cup for I the purposeof insulating it from said clamp,

my invention being directed generically to a portable lamp having tworetaining-casings inclosing the necessary battery and held together byretaining means which supports an electric lamp in circuit with thebattery.

It is obvious that there may be more than two battery-cells used in themanner hereinbefore described and that they might be placed side by sideinstead of the one upon the other, and also that the retaining-casingmight be of any conducting material and insulated on its exteriorsurface wholly by enamel or otherwise, as desired.

Having thus described my invention, what l claim, and desire to secureby Letters Patent of the United States, is

l. An electric lamp consisting` of a case comprising two parts ofconducting material insulated from each other and covered with externalinsulation, a lamp supported upon the case, and electrically connectedthereto, and a battery within the case, one of its terminals being inengagement with one part of the case, and the other adapted to beconnected with the other part thereof by means of a movablecircuit-closer, substantially as described.

2.
